Specification of Letters Patent.

Patented July 16. 1912-.

Application filed November 16, 1911. Serial No. 660,673.

provide means for driving each of the wheels of a motor vehicle.

A further object of the invention is to provide means for applying abrake to each of the wheels.

A still further object of the invention is to provide means for steeringthe front and rear wheels of the vehicle.

A still furtherobjeot of the invention'is to provide means whereby themovement ofthe steering wheels which while consonant-1y steering thefront and rear wheels will move the front wheel in advance of the rearwheel.

In the drawings :Figure 1 is a side elevation of a carequipped with theimproved driving mechanism. Fig. 2 is a top plan view, the body of thecar being removed. Fig. 8 is a detail view of the steering mechanism andFig. 4 adetail view of the same removed from the box.

In the drawings 10 designates the body of the car which is supported atthree points by the springs 11, 12, 14 and 15. The motor may be of anydesired construction and drives a shaft 17 which extends longitudinallyof the car, its end portion being provided with a pinion 18 disposeddirectly above a gear box 19 and in mesh with a pinion 20 on thevertically disposed drivenshaft 21. The shaft 21 drives a secondlongitudinally disposed shaft 26 which ex-" tends within the gear boxes19 and driving the front and rear axles. This driven shaft issupportedbysleeves 27 and 28, the longer sleeve 28-beingformed with the enlargedend portion 29. which receives the end portion of the shorter sleeve 27.The sleeves being connected to the bolsters by struts 30, thisarrangement of the sleeves allowing the front and rear axles totiltindependently as the car passes over an obstruction. The (ll'lVGshaft 1s provided with the universal joints 21 which allow-for thistilting. p

The front and rear wheels are steered by means of rods 47 whichare/actuated by levers 48 and 49, the lever 48 being con-' nected to theshort link and-the lever- 49 being connected to the long link 51. Thelink 50 is connected to the arm 52 and the link 5l' to the arm. 53,the'arm 52 being mounted on a shaft 5 1- which extends within thesteering box 55', the arm 53 being mounted upon the shaft 56 whichextends within the said steering box. Arranged on the shaft 54 is thesegment 57 which meshes with a worm 59 which is arranged adjacent theend of the steering staff 60, the end of said stafi' being supported bythe lower portion of the box 55. Arranged on the shaft 56 is a segment61 which meshes with a worm 62 positioned on the shaft 60. It

will be noted that as. the shaft is rotated the worms will impartmovement to the segments which will in turn move the levers to steer thefront and rear axles,the worm 59 which meshes with the segment 57imparti'ng movementto the front wheels and the worm 62imparting'movementto the rear wheels. In order that the front wheels maybe turned in advance of the rear wheels the worm 62 is provided with theportions 63 which are concentric with the shaft 60. Thus as the shaft isrotated movement will first be imparted to the segment 57, the rotationof said segment occurring slightly in advance of the rotation of thesegment 61.

It will be noted that in a constru'ction of this character each of theWheels will be driven separately in a simple and convenientmanner, means'being,provided for simultaneously applying 'the brake to all of thewheels, the'steering means being such which while 'consonantly steeringthe front and rear axles, the same imparts movement to the front wheelsin advance of the movement which is imparted to the rear.

wheels.

It will be noted that the entire construction is such as ma be easilyand economically manufacture readily assembled.

.lVhat is claimed is 1. In a controlling mechanism for motor vehicles,steering leversconhccted to the front and rear wheels, means forconsonantly moving all of said levers, and means the various parts beingfor imparting movement to the lever which actuates the front wheels, inadvance of the movement imparted to the rear wheels.

2. In a controlling mechanism for motor vehicles, levers connected tothe front and rear steering bars, a plurality of shafts, segmentsmounted upon each of said shafts, a link connection between eachsegment, and a corresponding lever, a steering post, worms mounted uponsaid post and adapted to impart movement to said segments, one of saidworms being formed with portions which are concentric WltlithB post.

3. In a controlling mechanism for motor vehicles, steering leversconnected to the front and rear steering bars, a plurality of segments,a connection between each of said segments and a corresponding lever,and a steering post which when rotated imparts movement to said leversthrough said segments, one of said levers being actuated in advance ofthe other.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
